The ECU has been designed as a component manufacturer (strong, resistant to several possibilities, eg shock resistance, tolerance to voltage / current changes). But still can not guarantee the endurance ECU.
Most complained of damage, his car did not want to live. For starters it is difficult, but in a good ignition system there is no obstacle. This allows the mechanics to understand where the damage if examined is still not alive.
In general, the cause of ECU damage is divided into two.
Damage from within the EFI system itself and damage from outside the system. Damage from within the system itself The quality of ecu components, although small, may occur, but for ECUs in cars older than 10 years, this can occur mainly in capacitor components, and resistors.
Added vehicle accessories. such as lights, power amplifiers and others that are not true will make the supply voltage and current on the ECU will be reduced, so the ECU function will be disrupted. The wrong sensor or actuator part (shorting to ground or + 12V) but not immediately fixed can also cause more damage.
A surrogate sensor that does not match its original characteristics. Incorrect installation of piggyback (tool for sensor manipulation). Damage from outside the ECU system is damaged by impact with severe flooding, either through washing or flooding.
Cars are in extreme environments, such as environments with high humidity, or salt-containing air. The car is in an environment with high levels of electromagnetic wave radiation. Because the ECU consists of discrete circuits (IC), then this component is very sensitive to electromagnetic. An example is the impact of lightning strikes, such as cars parked near trees struck by lightning, most likely the electromagnetic field waves will damage the ECU.
